Charles H. Spurgeon on Psalms 100:2

Serve the LORD. It is our privilege to serve the Lord in all things. It is ours to please the Lord in loosing the latchet of a shoe; and to enjoy the expression of his favour therein. The servant of God is not serving at the same time another master; he has not been hired for occasional service; he abides in the service of his God, and cannot be about anything but his Master's business; he eats, he drinks, he sleeps, he walks, he discourses, he findeth recreation, all by the way of serving God. Serve the Lord with gladness. Can you bear to be waited upon by a servant who goes moping and dejected to his every task? You would rather have no servant at all, than one who evidently finds your service cheerless and irksome. George Bowen.
